Influence of self-esteem and negative affectivity on oral health related quality of life in patients with partial tooth loss

Research output: Contribution to journalJournal article

To meaningfully interpret oral health-related quality of life
(OHRQoL) measures, the influence of personality traits must be investigated.
Objectives:To investigate and quantify the influence of self-esteem and negative
affectivity (NA) on OHRQoL. It was hypothesized that low self-esteem and
high NA would be associated with worse OHRQoL.Methods: OHRQoL
measured by the Oral Health Impact Profile 49 (OHIP-49), self-esteem
measured by the Rosenberg Self-Esteem Scale (RSES), NA measured by the
Eysenck Personality Inventory Questionnaire (EPI-Q), global oral rating of oral
comfort and controlling variables (gender, age, number of teeth, experience of
wearing removable dental prostheses (RDP), location of missing teeth and zone
of missing teeth) were collected from 81 patients with partial tooth loss, signed
in for treatment with RDP. Results:Bivariate analyses showed that the EPI-Q
score had the highest correlation with OHIP-49 score ( R = 0.5). Both EPI-Q and
RSES score had a stronger correlation with psychosocial items than physical/
functional items of the OHIP-49. In the multivariate analyses, the controlling
variables alone explained 17.75% of the variance in OHIP-49 score, while
addition of EPI-Q score, RSES score and both EPI-Q and RSES score explained
additionally 11.64%, 6.07% and 14.12%, respectively. For each unit increase in
EPI-Q score, the OHIP-49 score increased 5.1 units and for each unit increase in
RSES score, the OHIP-49 score decreased 1.1. NA was statistically and clinically
significantly higher and self-esteem was statistically significantly lower in
patients reporting worse oral comfort. Conclusion: NA had the strongest and
most clinically meaningful influence, but both NA and self-esteem was found
to influence OHRQoL; low self-esteem and high NA was associated with worse
OHRQoL. This indicates the possibility to explain some of the impact of tooth
loss on OHRQoL based on personality traits.
